(Received: May 11, 2014; Revised manuscript received: June 2, 2014; Accepted: June 2, 2014) Abstract: Introduction: Percutaneous interventional procedures in the renal arteries are usually performed using a femoral or brachial vascular access. The transradial approach is becoming more popular for peripheral interventions, but limited data exists for renal artery angioplasty and stenting. Methods: We have analyzed the clinical, angiographic and technical results of renal artery stenting performed from radial artery access between 2012 and 2013. The radial artery anatomy was identified with aortography using 100 cm pig tail catheter. After engagement of the renal artery ostium with a 6F Multipurpose or 6F JR5 guiding catheter, the stenosis was passed with a 0.014” guidewire followed by angioplasty and stent implantation. Results: In 27 patients (mean age: 65.4 ± 9.17) with hemodynamically relevant renal artery stenosis (mean diameter stenosis: 77.7 ± 10.6%; right, n = 7; left, n = 20), interventional treatment with angioplasty and stenting was performed using a left (n = 3) or right (n = 24) radial artery access. Direct stenting was successfully performed in 13 (48%) cases, and predilatations were required in ten cases 10 (37%). Primary technical success (residual stenosis
